Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed January 30. 1907,. I Serial No. 354,837.

S ringfield, in the county of Clark and State 0 Ohio, have invented certain new and useful Improvements in Disk-Bearings, of WlllCll the following is a specification, referencebeings. The present invention relates to disk bearmgs such as are employed in disks used in ing had therein to the accompanying drawconnection with agricultural implements,

such as disk furrow openers for grain drills and the like.

The object of the invention is to produce a bearing of this character which will be absolutely dust-proof and will be self lubricating, thereby providing a smooth easy running bearing and greatly extending the life of the same.

A further Object is to produce such a bearing of as simple a construction as is possible, thereby reducing the cost and avoiding an unwieldy or overweighted disk.

With these objects in viewthe resent invention consists of certain novel eatures of construction hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a grain drill embodying my invention; Fig.2 is a similar view of the same, with the diskremoved, Fig. 3 is a horizontal sectional view, taken centrally through the disk of Fig. 1; Fig. 1 is a vertical sectional view takenon the line a: .r

' of Fig. 3 and Fig; 5 is a side elevation of the hub and bearing block, with the cap removed.

In these drawings I have shown a portion of a disk grain drill and have embodied in the same one form of my invention.

The reference numeral 1 indicates the usual drag bar provided with a supporting bracket 2, upon which is mounted the usual gramconduit or boot3. The support 2 is' provided with an a erture 4 adapted to receive a screw-threa ed bolt 5, the inner end of which is adapted to engage a threaded app erture in abear ing block-6 and t0 rigidlysecure the same to the support 2Q The support 2 is provided'with an angular recess 7 surrounding the aperture 4 which is adapted to receivethe s uared lug 8 on the outer end 55..o f the bearing lock 6 to prevent t'heqsame from turning relatively to the support. The support is further rovided with an annu lar recess 9 surroun ing the aperture 4 and separated from the same by a projection or flange 10 and has its outer wall extended inwardly, as shown at 11, to forlnan annular flange; i The hub 12 is ri idly secured to the disk 13 13 by means of suitable rivets or bolts 15 and provided with an inwardly extending sleeve 16 adapted to extend through sin aperture 17 formed in the disk 13 and to have its inner end seated in the annular recess 9 in the support 2. That portion of the sleeve 16 which enters the recess 9 is preferably rabbeted or cut away, as shown .at 18, to form a recess to receive a packing 1 of felt or other suitable and. comprises a p ate 14 secured tothe disk material, which extends over the .joint formed between the bearing sleeve 16 and the bearing block 6 to prevent the entrance of dust or foreign material. The bearing sleeve 16, which extends through the a erture 17 in the disk; is of less diameter tian. said disk and thereby provides an annular recess or groove 20 between the inner edge of the dlsk and said bearing sleeve, said annular groove being adapted to receive the; inner end of the flange 1 l surrounding the annular recess Jon the support 2, thus rendering it practically impossible for dust or foreign material to enter the recess in the'support. Thebearing plate. 14 is further provided with an outward y extending annular flange 21 having its inner wall adapted to form a bearing.

surface to cooperate with the bearing surface formed by the periphery of the enlarged head 22 of the bearing block 6.

A cap 23 having an inwardly extending flung-e24 fits over the annular flange 21 and is rigidly secured thereto by means of bolts 25, extending through apcrtured lugs 26' formed on the cap. The heads of, saidbolts are secured to the plate 14, preferably by inserting the same in T-shaped slots 27 and the outer ends of the same areprovided with suitable nuts 27. A suitable packing 2-8 is inserted between the outer edge of the flange.

21 and the cap torende'r the same more completely dust-proof.

I The ca 23 is provided with a central screw-threa ed aperture 29 which is normally closed bya screw-- threaded plug 30 and isadapted to receive the discharge nozzle of a charging on for filling the oil receptacle 31 formed in t e bear-110 ing block 6 with an oil or lubricant. This oil receptacle 31 is directly connected with the bearing surfaces by the oil ducts or apertures 32, preferably leadin to the angle of the bearing, thereby fee in the lubricant directly to all arts of the bearing surface and uniformly lu ricating the same.

From the foregoing description it will be obvious that the bearing therein described is practically dust-proof, there being but two possible ways in which dust could gain access 'to the bearing, and both of these ways being guarded by overlapping flanges and suitable paekings, the entrance of foreign matter is rendered practically impossible. It will be further observed that the disk and its bearing is readily detached from the support 2 by removing-the screw 5 and that by the loosening of the nuts 27 on the bolts 25 the cap 23 may be removed to give access to the interior of the bearing; and'it will be further observed that the bearingis provided with. means for thoroughly lubricating all parts of the bearing surfaces by feeding the lubricant directly thereto from the receptacle formed in the bearing block as distinguished from th old method in which the oil was obliged to pass around the flange of the bearing block and thus work its way to the dill'erent parts of the bearing, a method which usually resulted in an overlubrication of the parts adjacent to the oil receptacle and in allowing those parts remote from said receptacle to run dry. It will also be noticed that the packing 19 in the rabbeted portion 18 of the sleeve 16 of the hub extends over the joint between the sleeve 16 and the bearing block 6 and is provided with a horizontal support to retain it in the proper position and to pro.- vent its disarrangement by the loose movementor the hub relatively to the support, so that it at all times occupies such a position as to prevent dirt from entering the bearing as distinguished from the old form in whichthe packing was supported between vertical surfaces and the movement of these surfaces relatively one to-the other disarrangcd the packing and permitted dirt to enter the bearg- V I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art. r

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent, is:
